Some books hold their place in history as legendary for their impact on society. Charles Darwin authored many of these books. "The Descent of Man" is a re-publishing of his work, with abridging and introduction from Michael Ghiselin. A follow up on "On the Origin of Species", Darwin continues to discuss the roots of humanity, sharing ancestors with apes and other primates, a claim which has earned Darwin notoriety and praise alike. "The Descent of Man" is a must for anyone who wants to read Darwin's work themselves, highly recommended.
